Hey, it's great to find another Arcturus fan (I found one on WTF too
)! Although I really liked Garm's voice, I can't help but to revere Vortex's vocal abilities... His voice is a true gift, and even the songs from their previoous albums sound great with it!
And yes, Mikael is indeed an awesome frontman. When I saw them live in December 2006 (already with Axenrot, also), he even made Mendez play a Michael Jackson's bass line... I guess it's on Youtube, too!
